In the cross between two heterozygous in a dihybrid cross, according to Mandel's statement is expected that the proportion of the phenotype ratio of the offspring be 9:3:3:1. Since the pugs with fawn fur and short ears have the genotype wwee, and considering Mendel's studies and the application of the Punnett Square, the proportion of the offspring with fawn fur and short ears is 6,25% or 1/16.
